Overview
The MAC 52A-11-B0A-DM-DFFJ-1KJ solenoid valve is a pilot-operated 3-way balanced spool valve from MAC’s 52 Series. This model features a direct-operated 4-way solenoid control pilot, delivering low minimum operating pressure and smooth flow control for pneumatic applications. The valve is equipped with a 24VDC coil assembly (DMB-DFFJ-1KJ) and 1/4″ NPTF threaded ports, making it suitable for integration into existing pneumatic system layouts.
Key Features
- 3-way balanced spool design with pilot-operated actuation for consistent performance across pressure ranges
- 4-way pilot solenoid provides low minimum operating pressure and reduced control power draw
- 24 VDC coil (DMB-DFFJ-1KJ) with nominal wattage consumption
- 1/4″ NPTF ports for direct integration into standard pneumatic manifolds and systems
- Internal pilot air reference for self-contained operation
- Non-locking recessed manual override for maintenance and emergency manual control
